Process industries face continuous competition in enhancing productivity and efficiency, improving plant asset availability, avoiding unplanned outages, and managing plant safety. These industry users also face a wide range of operational challenges in cybersecurity as a pervasive threat to safety and availability. Most companies take a relatively simplistic plant-by-plant approach in implementing operating system security patches and anti-virus pattern file updates. As a result, security levels tend to vary at each plant.

Process industries face continuous competition in enhancing productivity and efficiency, improving plant asset
availability, avoiding unplanned outages, and managing plant safety. These industry users also face a wide range of
operational challenges in cybersecurity as a pervasive threat to safety and availability. Most companies take a
relatively simplistic plant-by-plant approach in implementing operating system security patches and anti-virus
pattern file updates. As a result, security levels tend to vary at each plant.
As a leader in mission-critical plant automation systems, Yokogawa has established various Operational Technology
(OT) solutions to address the variety of demands in process control operations. Industrial markets seek to further
leverage these solutions with Internet-based technologies, but without the potential pitfalls. Through integration
with the Industrial Internet-Of-Things (IIoT) into Yokogawa enterprise solutions, users can even further reduce
critical asset downtime, improve plant productivity as well as speed of response and service.
